Participant Flow

The study was conducted at multiple centers in 12 countries worldwide between 15 May 2014 (first subject first visit) and 04 May 2016 (last subject last visit).

748 subjects were screened; 439 subjects were not randomized, the majority was screen failures. Therefore, 309 subjects were randomized.

Timeframe: From baseline to end of follow-up period

Pelvic Magnetic resonance imagings (MRI), without contrast agents, were performed for volume measurements of the uterus and fibroids preferably using 1.5 Tesla scanners or higher. Images were sent to the imaging core laboratory for evaluation. Volume measurements of the uterus and fibroids were performed centrally by independent radiologist(s).

Population: The exposure response analysis includes all verum treated subjects with valid PK concentration data and valid PD data and all placebo treated subjects with valid PD data (placebo: 50, 0.5 mg 50, 1.0 mg 56, 2.0 mg: 56, 4.0 mg: 55, in total 267).

Maximum effect of vilaprisan on induced amenorrhea during treatment period. Induced amenorrhea was defined as number of subjects with amenorrhea (that is, all days with bleeding intensity 1 = none) , i.e. no bleeding or spotting allowed after initial bleeding episode until end of treatment. The nature of this exposure response analysis was the development of a model valid for the exposure response relationship over the entire range of available exposures (i.e. across all dose groups). Therefore, observations (exposure - induced amenorrhea) of all subjects need to be combined.

Timeframe: At baseline

Population: An analysis set for the assessment of the interchangeability of the MP and the AH method to judge MBL included all screened subjects (except subjects in Japan) with any sanitary product data for which there is any matching pair of MP score and AH value available. A total of 399 subjects were included in this analysis set.

The ability of the MP to identify subjects with HMB (defined as \> 80 mL of blood loss during bleeding episode) per 28 days against the the current gold standard (i.e. AH method) was assessed. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of MP method for detecting heavy menstrual bleeding were calculated against AH method. Sensitivity = true positive/(true positive + false negative)\*100; Specificity = true negative/(true negative + false positive)\*100; PPV = true positive/(true positive + false positive)\*100; NPV = true negative/(true negative + false negative)\*100. MP version 2014 was originally defined based on studies in healthy subjects. And MP version 2016 was developed for study population of women with heavy bleeding.

OTHER_PRE_SPECIFIED outcome

Timeframe: After end of the initial bleeding episode until the end of treatment

The primary objective was to estimate the dose-response curve based on the primary endpoint: subjects with amenorrhea. The number of subjects with amenorrhea was assumed to be binomial distributed. A 4 parameters logistic model was used to fit the observed data for characterizing the dose-response curve: E0, Emax, ED50 and δ. The model is defined as p(d)=E0 + Emax/{1+ e\^\[{ED50-d)/δ\]}. E0 is the amenorrhea rate for placebo; Emax is the maximum effect attributable to the drug (compared with the basal effect with dose at d=0 \[placebo group\], the maximum increase of drug effect).

The primary objective was to estimate the dose-response curve based on the primary endpoint: subjects with amenorrhea. The number of subjects with amenorrhea was assumed to be binomial distributed. A 4 parameters logistic model was used to fit the observed data for characterizing the dose-response curve: E0, Emax, ED50 and δ. The model is defined as p(d)=E0 + Emax/{1+ e\^\[{ED50-d)/δ\]}. ED50 is the dose at which 50% of Emax were achieved.

Timeframe: After end of the initial bleeding episode until the end of treatment

The primary objective was to estimate the dose-response curve based on the primary endpoint: subjects with amenorrhea. The number of subjects with amenorrhea was assumed to be binomial distributed. A 4 parameters logistic model was used to fit the observed data for characterizing the dose-response curve: E0, Emax, ED50 and δ. The model is defined as p(d)=E0 + Emax/{1+ e\^\[{ED50-d)/δ\]}. δ is hill slope parameter which measures sensitivity of the response to the dose range of the drug, determining the steepness of the dose-response curve.
